If the specified delay is very short, the cycle counter may go past the
"end" time we are waiting for before we get around to reading it.
Fix it by checking the different between the cycle count "now" and the
cycle count at the beginning. This will work as long as the delay
measured in number of cycles is below 2^31.

This cleans up the SDRAM initialization and related code a bit, and
allows faster booting.
* Add definitions for EBI and internal SRAM to asm/arch/memory-map.h
* Remove memory test from sdram_init() and make caller responsible
for verifying the SDRAM and determining its size.
* Remove base_address member from struct sdram_config (was sdram_info)
* Add data_bits member to struct sdram_config and kill CFG_SDRAM_16BIT
* Add support for a common STK1000 hack: 16MB SDRAM instead of 8.

Since the reset vector is always aligned to a very large boundary, we
can save a couple of KB worth of alignment padding by placing the
exception vectors at the same address.
Deciding which one it is is easy: If we're handling an exception, the
CPU is in Exception mode. If we're starting up after reset, the CPU is
in Supervisor mode. So this adds a very minimal overhead to the reset
path (only executed once) and the exception handling path (normally
never executed at all.)

pm_init() was always more about clock initialization than anything
else. Dealing with PLLs, clock gating and such is also inherently
SoC-specific, so move it into a SoC-specific directory.

Rework the HMATRIX configuration interface so that it becomes easier
to configure the HMATRIX for boards with special needs, and add new
parts.
The HMATRIX header file has been split into a general,
chip-independent part with register definitions, etc. and a
chip-specific part with SFR bitfield definitions and master/slave
identifiers.

The .flashprog section was only needed back when we were running
directly from flash, and it's even more useless on NGW100 since it
uses the CFI flash driver which never used this workaround in the
first place.
Remove it on STK1000 as well, and get rid of all the associated code and
annotations.

This patch forces the watchdog off in all cases. That will at least
get rid of the constant reboot cycle, though it won't let the watchdog
actually run in the new kernels: its probe() comes up with a polite
warning.

Make STK1002 and NGW100 boards act more alike:
- STK boards can use as many arguments as NGW
- STK boards don't need to manage FPGAs either
- NGW commands should match STK ones
Also spell U-Boot right in prompts for STK1002 and NGW100.
